Cochlear Implant Impedance Fluctuation in Ménière's Disease

Abstract

Electrode impedances in the ear with MD showed a variation pattern similar to that found in the hearing fluctuation characteristic of the disease. These findings raise the possibility that the same physiological mechanisms of hearing fluctuation may be responsible for intracochlear electrode impedance changes. We hypothesize that impedance fluctuation is because of changes in the permeability of the blood-labyrinth barrier because of cyclic immune activity in the inner ear which alters the electrical resistance between scala tympani and blood.

Current Understanding and Clinical Management of Meniere's Disease: A Systematic Review

“…Uncontrolled studies have shown that cochlear implants in MD can improve hearing, tinnitus, and vestibular function. [114][115][116][117] -Meniett device: This therapy consists of an aural device that applies pulses of low positive pressure, with the hypothesis that these changes stabilize the pressure in the inner ear. Their results are controversial.…”

Cochlear Implantation in Meniere's Disease: A Systematic Review and Meta‐Analysis

“…Of 37 studies included, 32 (86.5%) studies were full manuscripts [8][9][10][11][12][13] and five (13.5%) were conference abstracts. [43][44][45][46][47] 21 (56.8%) papers were case series (more than one patient), [19][20][21][22][25][26][27][28][29][30]36,37,40,[43][44][45][46][47] 11 (29.7%) were case reports (one patient), 23,24,[30][31][32][33][34][35]38,39,41,42 and five (13.5%) were case-control studies (one or more comparison groups). [8][9][10][11][12] Twenty-five (67.6%) studies were based internationally and 12 (32.4%) studies were based in the United States (Table I).…”

Cochlear Implant Merits in Patients with Meniere’s Disease

“…McNeil C, et al [30] described a patient with bilateral sensorineural hearing loss with unilateral MD who had undergone bilateral CI; they noted that fluctuation of hearing is recurring postoperatively in MD ear following CI.…”
